Description

Technical Field

[0001] This disclosure relates to the field of computer hardware technology, specifically to a hinge assembly and electronic device. Background Technology

[0002] Existing dual-axis simultaneous hinge designs for laptops, such as Figure 6 (a) and Figure 8 As shown, when the display and system are flipped relative to each other, the display screen rises, widening the bezels visible to the user (reducing the screen-to-body ratio). This is unsuitable for user designs that prioritize a high screen-to-body ratio, resulting in a poor user experience. Furthermore, in existing technologies, when the display is flipped to a normal user angle, a rubber pad needs to be added to the hinge to prevent it from sagging and damaging the electronic device. This increases the overall size of the hinge, raising manufacturing costs, and the added component also negatively impacts the overall aesthetics of the laptop. Summary of the Invention

[0003] This disclosure provides a hinge assembly and an electronic device that can solve the problem in the prior art that cannot meet the user's demand for a high screen-to-body ratio and requires additional rubber pads to prevent the hinge from sinking and touching the desktop.

[0004] According to one of the solutions disclosed herein, a pivot assembly is provided for connecting a first body and a second body, comprising:

[0005] The first rotating shaft is connected to the first body.

[0006] The second rotating shaft is connected to the second body.

[0007] A synchronous mechanism is located between the first rotating shaft and the second rotating shaft, and is connected to the first rotating shaft and the second rotating shaft respectively for transmission.

[0008] The control mechanism includes a first follower sleeved on the first rotating shaft, a second follower sleeved on the second rotating shaft, and a locking member disposed between the first rotating shaft and the second rotating shaft. When the first body and the second body are in a first state of relative flipping, the locking member acts with the first follower or the second follower to fix the first rotating shaft or the second rotating shaft. When the first body and the second body are in a second state of relative flipping, the locking member and the actions of the first follower and the second follower are both released, and the first rotating shaft and the second rotating shaft rotate synchronously through the co-movement mechanism.

[0009] In some embodiments, the first follower has a first protrusion and a first groove that cooperate with the locking member, and the second follower has a second protrusion and a second groove that cooperate with the locking member. When the first body and the second body are in a first state of relative flipping, the first protrusion or the second protrusion abuts against the locking member. When the first body and the second body are in a second state of relative flipping, the first groove and the second groove face the locking member and have gaps between them respectively.

[0010] In some embodiments, the first follower further includes a first arcuate profile disposed between the first protrusion and the first groove to interact with the locking member and drive the locking member to move toward the first rotating shaft when the first rotating shaft rotates; the second follower further includes a second arcuate profile disposed between the second protrusion and the second groove to interact with the locking member and drive the locking member to move toward the second rotating shaft when the second rotating shaft rotates.

[0011] In some embodiments, the transmission sections on the first and second rotating shafts that cooperate with the synchronous mechanism are respectively provided with a first helical groove and a second helical groove. The first and second helical grooves are correspondingly arranged and have opposite helical directions. The synchronous mechanism has a first end and a second end. The first end is embedded in the first helical groove and the second end is embedded in the second helical groove. After the action of the follower and the locking member is released, the first shaft and the second shaft can be synchronously rotated by the movement of the first end along the first helical groove and the movement of the second end along the second helical groove.

[0012] In some embodiments, the transmission sections on the first and second rotating shafts that cooperate with the co-movement mechanism are respectively provided with a first annular groove and a second annular groove. The first annular groove is connected to the first spiral groove, and the second annular groove is connected to the second spiral groove. When one of the first and second rotating shafts is fixed and the other rotates, the first end of the co-movement mechanism moves along the first annular groove of the rotating first rotating shaft, or the second end of the co-movement mechanism moves along the second annular groove of the rotating second rotating shaft.

[0013] In some embodiments, the rotating shaft assembly further includes a first bushing sleeved on a first transmission section of the first rotating shaft and a second bushing sleeved on a second transmission section of the second rotating shaft, wherein the first helical groove and the first annular groove are formed on the outer periphery of the first bushing sleeve, and the second helical groove and the second annular groove are formed on the outer periphery of the second bushing sleeve.

[0014] In some embodiments, the co-movement mechanism and the locking member are coaxially connected; the rotating shaft assembly further includes at least one connector simultaneously sleeved on the first rotating shaft and the second rotating shaft, the connector being located at least between the co-movement mechanism and the locking member.

[0015] In some embodiments, the rotating shaft assembly further includes a first fixing frame and a second fixing frame, wherein one end of the first rotating shaft is connected to the first body through the first fixing frame, and one end of the second rotating shaft is connected to the second body through the second fixing frame.

[0016] In some embodiments, the locking element is an elastic element.

[0017] According to one of the solutions disclosed herein, an electronic device is also provided, including the aforementioned hinge assembly. The electronic device further includes a first body and a second body, the first body and the second body being connected by relative flipping via the hinge assembly.

[0018] The various embodiments of this disclosure provide a hinge assembly and electronic device. By setting a first hinge and a second hinge respectively connected to a first body and a second body, and driving the first hinge and the second hinge together through a synchronous mechanism, and setting a control mechanism between the first hinge and the second hinge, during the relative flipping of the first body and the second body, the cooperation of the follower and locking member in the control mechanism can realize the individual rotation of the first hinge or the second hinge, or the synchronous rotation of the first hinge and the second hinge. In this way, during the relative flipping of the first body and the second body, the screen (first body) can be sunk, meeting the user's demand for a high screen-to-body ratio; and the first body will not come into contact with a flat surface such as a desktop. Thus, there is no need to add an extra rubber pad, which can effectively reduce the manufacturing cost of electronic devices, and the product has a simple and beautiful appearance.

[0037] Figures 1 to 4 A schematic diagram of the structure of the rotating shaft assembly according to an embodiment of the present disclosure is shown; Figure 5 A schematic diagram of the operation of the rotating shaft assembly according to an embodiment of this disclosure is shown. Figures 1 to 5 As shown, this embodiment of the disclosure provides a pivot assembly 10 for connecting a first body 20 and a second body 30, including:

[0038] The first rotating shaft 1 is connected to the first body 20;

[0039] The second rotating shaft 2 is connected to the second body 30;

[0040] The synchronous mechanism 3 is located between the first rotating shaft 1 and the second rotating shaft 2, and is connected to the first rotating shaft 1 and the second rotating shaft 2 respectively for transmission.

[0041] The control mechanism includes a first follower 41 sleeved on the first rotating shaft 1, a second follower 42 sleeved on the second rotating shaft 2, and a locking member 43 disposed between the first rotating shaft 1 and the second rotating shaft 2. When the first body 1 and the second body 2 are in a first state of relative flipping, the locking member 43 and the first follower 41 or the second follower 42 work together to fix the first rotating shaft 1 or the second rotating shaft 2. When the first body 1 and the second body 2 are in a second state of relative flipping, the locking member 43 and the first follower 41 and the second follower 42 are both released, and the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously through the synchronous movement mechanism 3.

[0042] The first body 20 is the display end of the laptop computer, and the second body 30 is the system end of the laptop computer.

[0043] The rotating shaft assembly 10 provided in this embodiment of the present disclosure is provided with a first rotating shaft 1 and a second rotating shaft 2 respectively connected to a first body 20 and a second body 30, and the first rotating shaft 1 and the second rotating shaft 2 are connected by a synchronous mechanism 3. At the same time, a control mechanism is provided between the first rotating shaft 1 and the second rotating shaft 2. During the relative flipping of the first body 20 and the second body 30, the first rotating shaft 1 or the second rotating shaft 2 can be rotated individually or synchronously by the cooperation of the follower and locking member 43 in the control mechanism. In this way, during the relative flipping of the first body 20 and the second body 30, the screen (first body 20) can be sunk to meet the user's demand for a high screen-to-body ratio; and the first body 20 will not come into contact with a flat surface such as a desktop. Thus, there is no need to add an extra rubber pad, which can effectively reduce the manufacturing cost of electronic devices, and the product has a simple and beautiful appearance.

[0044] In some embodiments, such as Figures 1 to 4 As shown, the first follower 41 is provided with a first protrusion 411 and a first groove 412 that cooperate with the locking member 43. The second follower 42 is provided with a second protrusion 421 and a second groove 422 that cooperate with the locking member 43. When the first body 20 and the second body 30 are in a first state of relative flipping, the first protrusion 411 or the second protrusion 421 abuts against the locking member 43 to fix the first rotating shaft 1 or the second rotating shaft 2, thereby allowing the second rotating shaft 2 or the first rotating shaft 1 to rotate independently. When the first body 20 and the second body 30 are in a second state of relative flipping, the first groove 412 and the second groove 422 face the locking member 43 and have a gap 5 between them, thereby releasing the action of the locking member 43 on the first follower 41 and the second follower 42.

[0045] Specifically, the first follower 41 and the second follower 42 are respectively sleeved on the first rotating shaft 1 and the second rotating shaft 2. When the first body 20 and the third body 30 rotate relative to each other, causing the first rotating shaft 1 or the second rotating shaft 2 to rotate, they can drive the first follower 41 sleeved on the first rotating shaft 1 or the second follower 42 sleeved on the second rotating shaft 2 to rotate synchronously. When the first follower 41 rotates to the point that the first protrusion 411 abuts against the locking member 43, the first rotating shaft 1 can be fixed, and at this time the first rotating shaft 1 can no longer rotate. When the first follower 41 rotates to the point where the first groove 412 is opposite to the locking member 43, the gap 5 between the first groove 412 and the locking member 43 releases the action of the first rotating shaft 1 and the locking member 43, meaning the locking member 43 cannot fix the first rotating shaft 1. At this time, if the second rotating shaft 2 is rotating, and the second groove 412 of the second rotating shaft 2 is opposite to the locking member 43, the rotation of the second rotating shaft 2 can drive the first rotating shaft 1 to rotate synchronously with the second rotating shaft 2 through the synchronous mechanism 3. The cooperation between the second protrusion 421 and the second groove 422 of the second follower 42 and the locking member 43 is similar to that of the first follower 41 described above, and will not be repeated here.

[0046] In particular, such as Figure 4 As shown, the first follower 41 also includes a first arcuate profile 413, which is disposed between the first protrusion 411 and the first groove 412. When the first follower 41 rotates with the first rotating shaft 1, it can interact with the locking member 43 through the first arcuate profile 413, so as to push the locking member 43 toward the first rotating shaft 1 when the first rotating shaft 1 rotates, and then fix the first rotating shaft 1 by the abutment between the first protrusion 411 and the locking member 43. Similarly, the second follower 42 also includes a second arcuate profile 423, which is disposed between the second protrusion 421 and the second groove 422. When the second follower 42 rotates with the second rotating shaft 2, it can interact with the locking member 43 through the second arcuate profile 423, so as to push the locking member 43 toward the second rotating shaft 2 when the second rotating shaft 2 rotates, and then fix the second rotating shaft 2 by the abutment between the second protrusion 421 and the locking member 43.

[0047] In one specific embodiment, such as Figure 2 As shown, when the first rotating shaft 1 is fixed and the second groove portion 422 of the second rotating shaft 2 faces the locking member 43, the second rotating shaft 2 can rotate independently. When the second rotating shaft 2 rotates, it acts on the locking member 43 through the second arc-shaped contour 423, pushing the locking member 43. Due to the arc shape of the second arc-shaped contour 423, a cam structure can be formed, so that the locking member 43 reacts to the second follower 42 and moves the locking member 43 toward the second rotating shaft 2 by a first distance, thereby releasing the fixation of the first rotating shaft 1.

[0048] like Figure 3 and Figure 4 As shown, both the first groove portion 412 and the second groove portion 422 are arc-shaped groove portions to ensure the smooth rotation of the first rotating shaft 1 and the second rotating shaft 2 after the action of the locking member 43 is released.

[0049] In specific implementation, a first arc profile 413 and a second arc profile 423 can be set on the first follower 41 and the second follower 42, or multiple first arc profiles 413 and second arc profiles 423 can be set so that the first rotating shaft 1 and the second rotating shaft 2 can achieve relative flipping of the first body 20 and the second body 30 through multiple rotations.

[0050] In this embodiment, as Figure 3 and Figure 4 As shown, both the first follower 41 and the second follower 42 are irregularly shaped structures. The first protrusion 411, the first groove 412, and the first arc-shaped contour 413 of the first follower 41 are offset from the second protrusion 421, the second groove 422, and the second arc-shaped contour 423 of the second follower 42 relative to the locking member 43. This ensures the independent rotation of the first rotating shaft 1 and the second rotating shaft 2, as well as the synchronous rotation of the first rotating shaft 1 and the second rotating shaft 2. In other words, it prevents the first protrusion 411 and the second protrusion 421 from simultaneously abutting against the locking member 43, thus preventing the first rotating shaft 1 and the second rotating shaft 2 from rotating smoothly.

[0051] In this embodiment, the outer periphery of the locking member 43 is a circular annular structure, which interacts with the outer periphery of the first follower 41 and the second follower 42. The locking member 43 is preferably an elastic member to ensure the pushing effect of the first follower 41 and the second follower 42 on the locking member, so that the locking member 43 reciprocates between the first rotating shaft 1 and the second rotating shaft 2.

[0052] In some embodiments, such as Figure 2 As shown, the transmission sections on the first rotating shaft 1 and the second rotating shaft 2 that cooperate with the synchronous mechanism 3 are respectively provided with a first spiral groove 11 and a second spiral groove 21. The first spiral groove 11 and the second spiral groove 21 are arranged correspondingly and have opposite spiral directions. The synchronous mechanism 3 has a first end and a second end. The first end is embedded in the first spiral groove 11 and the second end is embedded in the second spiral groove 21. After the action of the first follower 41, the second follower 42 and the locking member 43 are all released, the first rotating shaft 1 and the second rotating shaft 2 can be synchronously rotated by the movement of the first end along the first spiral groove 11 and the movement of the second end along the second spiral groove 21.

[0053] Furthermore, such as Figure 2As shown, the transmission sections on the first rotating shaft 1 and the second rotating shaft 2 that cooperate with the co-movement mechanism 3 are respectively provided with a first annular groove 12 and a second annular groove 22. The first annular groove 12 is connected to the first spiral groove 11, and the second annular groove 22 is connected to the second spiral groove 21. When one of the first rotating shaft 1 and the second rotating shaft 2 is fixed and the other rotates, that is, when the first rotating shaft 1 rotates alone, the first end of the co-movement mechanism 3 moves along the first annular groove 12 of the first rotating shaft 1, or when the second rotating shaft 2 rotates alone, the second end of the co-movement mechanism 3 moves along the second annular groove 22 of the second rotating shaft 2, so as to ensure the independent rotation of the first rotating shaft 1 or the second rotating shaft 2.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotating shaft assembly 10 also includes a first bushing 61 fitted onto the first transmission section of the first rotating shaft 1 and a second bushing 62 fitted onto the second transmission section of the second rotating shaft 2. A first helical groove 11 and a first annular groove 12 are formed on the outer periphery of the first bushing 61, and a second helical groove 21 and a second annular groove 22 are formed on the outer periphery of the second bushing 62. By fitting bushings onto the rotating shaft and forming helical and annular grooves on the bushings, it is convenient to replace the helical and annular grooves of appropriate sizes according to actual rotation needs, without replacing the entire rotating shaft. This method is also convenient for processing and manufacturing, and provides some protection to the transmission section of the rotating shaft. Furthermore, the bushings provide a certain amount of torque for rotation.

[0055] In practice, spiral grooves and annular grooves can also be directly opened on the shafts of the first rotating shaft 1 and the second rotating shaft 2. In this way, when replacing them, the entire rotating shaft needs to be replaced, that is, different sizes of rotating shafts need to be configured for electronic devices of different sizes.

[0056] In some embodiments, such as Figure 2 As shown, the first control section (the shaft section corresponding to the locking member 43) of the first follower 41 and the first transmission section of the first bushing 61 are flat shaft sections on the first rotating shaft 1. The second control section of the second follower 42 and the second transmission section of the second bushing 62 are flat shaft sections on the second rotating shaft 2, ensuring a reliable connection between the first follower 41 and the first rotating shaft 1, and between the second follower 42 and the second rotating shaft 2.

[0057] In some embodiments, such as Figures 1 to 3 As shown, the co-moving mechanism 3 and the locking member 43 are coaxially connected; the rotating shaft assembly 10 also includes at least one connecting member 7 simultaneously sleeved on the first rotating shaft 1 and the second rotating shaft 2, the connecting member 7 being located at least between the co-moving mechanism 3 and the locking member 43 to separate the co-moving mechanism 3 and the locking member 43. In this embodiment, the first rotating shaft 1 and the second rotating shaft 2 are arranged parallel to each other and connected by at least one connecting member 7.

[0058] In some embodiments, the rotating shaft assembly 10 further includes a first fixing frame 81 and a second fixing frame 82, one end of the first rotating shaft 1 is connected to the first body 20 through the first fixing frame 81, and one end of the second rotating shaft 2 is connected to the second body 30 through the second fixing frame 82. Figures 1 to 4 As shown, when the rotating shaft assembly 10 is in its initial state, the first fixing bracket 81 and the second fixing bracket 82 are parallel to each other so that the first body 20 and the second body 30 are closed.

[0059] In this embodiment, the first fixed frame 81 is disposed close to the first transmission section of the first rotating shaft 1 and the second transmission section of the second rotating shaft 2, and a connecting piece 7 may also be sleeved between the first fixed frame 81 and the first transmission section and the second transmission section.

[0060] In some embodiments, the shaft assembly 10 further includes a torque mechanism 9 disposed on the first shaft 1 and the second shaft 2 respectively. The torque mechanism 9 is disposed at the other end of the first shaft 1 and the second shaft 2 (the end without the fixed frame) to provide torque for the rotation of the shaft assembly 10.

[0061] Figure 5 A schematic diagram of the operation of the rotating shaft assembly provided in this disclosure embodiment is shown, such as... Figure 5 As shown, combined with Figures 1 to 4 When the hinge assembly 10 is in its initial state, the first fixing bracket 81 and the second fixing bracket 82 are arranged in parallel, the laptop is in a closed state, and the first protrusion 411 of the first follower 41 sleeved on the first hinge 1 abuts against the locking member 43 to fix the first hinge 1. When the first body 20 is flipped, since the first hinge 1 and the second hinge 2 are connected as one unit by the connector 7, the second hinge 2 rotates with the first body 20 relative to the second body 30. When the second hinge 2 rotates, it acts on the locking member 43 through the second arc-shaped contour 423, causing the locking member 43 to move toward the second hinge 2. When the first body 20 is flipped to the position shown in the image, the first hinge 1 is closed. Figure 5 When the first angular position is shown in (a), the locking member 43 moves a first distance toward the second rotating shaft and then abuts against the second protrusion 421 of the second follower member 42, fixing the second rotating shaft 2. At the same time, the fixing effect between the first rotating shaft 1 and the locking member 43 is released. During the process of the first body 20 flipping to the first angular position, since the first rotating shaft 1 is fixed, as shown in (a), the locking member 43 moves a first distance toward the second rotating shaft 2. Figure 5As shown in (a), the first fixing bracket 81 is perpendicular to the line connecting the axes of the first rotating shaft 1 and the second rotating shaft 2, and the second fixing bracket 82 forms a first angle with the line connecting the axes of the first rotating shaft 1 and the second rotating shaft 2. This allows the first rotating shaft 1, which is connected to the first body 20, to be lowered, increasing the screen-to-body ratio and meeting user needs. When the action of the first rotating shaft 1 and the locking member 43 is released, the first rotating shaft 1 can rotate with the rotation of the first body 20. As the first rotating shaft 1 rotates, it interacts with the locking member 43 through the first arc-shaped contour 413, allowing the locking member 43 to move toward the first rotating shaft 1. When the first body 20 is rotated to the position shown in (a), the first rotating shaft 1 can rotate. Figure 5 When the second angular position shown in (b) is reached (e.g., 180° between the first body 20 and the second body 30), the locking member 43 moves a second distance toward the first rotating shaft 1 (the second distance is less than the first distance), thereby releasing the fixing effect between the second rotating shaft 1 and the locking member 43. Simultaneously, because the second distance is less than the first distance, the first protrusion 411 of the first follower 41 does not abut against the locking member 43, and the fixing effect between the first rotating shaft 1 and the locking member 43 remains released. Due to the rotation of the first rotating shaft 1, such as... Figure 5 As shown in (b), the first fixing frame 81 forms a second angle with the axis connecting the first rotating shaft 1 and the second rotating shaft 2, while the first angle between the second fixing frame 82 and the axis connecting the first rotating shaft 1 and the second rotating shaft 2 remains unchanged. When the fixing action between the first rotating shaft 1 and the locking member 43 is released, and the fixing action between the second rotating shaft 2 and the locking member 43 is released, the first rotating shaft 1 can be rotated by continuing to rotate the first body 20. Through the action of the first spiral groove 11 on the first rotating shaft 1 and the first end of the synchronous mechanism 3, the rotational force of the first rotating shaft 1 is transmitted to the second end through the first end. The second end, through the action of the second spiral groove 21 on the second rotating shaft 2, drives the second rotating shaft 2 to rotate, thereby realizing the synchronous rotation of the first rotating shaft 1 and the second rotating shaft 2, so that the first body 20 can rotate 360° relative to the second body 30. Figure 5 At the third angle position shown in (c), the first fixing frame 81 forms a third angle with the line connecting the axes of the first rotating shaft 1 and the second rotating shaft 2, and the second fixing frame 82 forms a fourth angle with the line connecting the axes of the first rotating shaft 1 and the second rotating shaft 2. The process of the first body 20 flipping relative to the second body 30 is the reverse of the above process, and will not be described again here.

[0062] The first angle position is one that allows the user to use the electronic device normally while preventing the hinge from touching the desktop. This first angle position can be set according to the user's actual needs; for example, it is preferably 90-160°. The second angle position is preferably 180°, and the third angle position is preferably 360°. As described above, the control mechanism can make the first hinge 1 or the second hinge 2 rotate independently, and cooperate with the synchronous mechanism 3 to make the first hinge 1 and the second hinge 2 rotate synchronously, realizing the 0-360° arbitrary angle flipping of the first body 20 and the second body 30. The hinge assembly structure is simple and reasonable, which can effectively improve the screen ratio for the user's viewing angle, and can prevent the hinge assembly from colliding with the desktop without the need for additional rubber pads, reducing the overall size and ensuring the aesthetic appearance of the electronic device.

[0063] In the above embodiments, the first body 20 and the second body 30 are achieved by first fixing the first rotating shaft 1 connected to the first body 20, rotating the second rotating shaft 2 separately to make the first body 20 rotate relative to the second body 30 by a first angle, fixing the second rotating shaft 2, and rotating the first rotating shaft 1 separately. After the first body 20 rotates relative to the second body 30 from the first angle to the second angle, the first rotating shaft 1 and the second rotating shaft 2 are made to rotate synchronously through the co-movement mechanism 3, thereby realizing the entire process of the first body 20 rotating relative to the second body 30.

[0064] In other embodiments, the first rotating shaft 1 and the second rotating shaft 2 can rotate synchronously by rotating only the first rotating shaft 1 or the second rotating shaft 2 individually. Specifically, taking the initial state described above, where the first rotating shaft 1 is fixed, the structure of the first follower 41 and the second follower 42 can be designed so that when the second rotating shaft 2 rotates alone and acts on the locking member 43, after the locking member 43 moves a first distance toward the second rotating shaft 2, the second protrusion 421 does not abut against the locking member 43, thereby releasing the fixing effect between the first rotating shaft 1 and the locking member 43, and releasing the fixing effect between the second rotating shaft 2 and the locking member 43.

[0065] Figures 6 to 8 The diagram shows a comparison of the operation of a rotating shaft assembly according to an embodiment of this disclosure with that of a prior art rotating shaft assembly, such as... Figures 6 to 8 As shown, in the process of the first body 20 and the second body 30 being flipped relative to each other, the hinge assembly 10 of this embodiment can make the screen (first body 20) sink down, increasing the screen ratio for the user's viewing; and the first body 20 will not come into contact with the desktop or other flat surfaces, eliminating the need for additional rubber pads, effectively reducing the manufacturing cost of electronic devices, and the product is simple and beautiful.

[0066] like Figure 5As shown, this disclosure also provides an electronic device including the aforementioned pivot assembly 10. The electronic device further includes a first body 20 and a second body 30, which are connected by a pivot assembly 10 and rotated relative to each other.

[0067] The electronic device is a laptop computer. The first body 20 is the display end, and the second body 30 is the system end. The display end is connected to the first rotating shaft 1 through the first fixing bracket 81, and the system end is connected to the second rotating shaft 2 through the second fixing bracket 82.
